Large-scale magnetic field configurations are important for the transport of solar wind strahl electrons, which are suprathermal and directed along the field outward from the Sun. Strahl electrons are routinely used to infer not only the field configurations between the Sun and Earth but also local field structures, i.e., field inversions, where the magnetic field is locally folded back or inve...

To optimize the capacity and positioning of the cleaning vessels, Genetic Algorithm is used for ports and coastal areas in the Persian Gulf due to economical and environmental damages. Local wind is recognized as the principal driving force to simulate the trajectory of oil spill events. In this regard, the wind field is determined by Weibull probability distribution to adjust the prevailing wi...

in the current research, wind energy potential at yazd synoptic stations, which contain wind data with 10 years statistic period and beyond, including yazd synoptic station (1976-2006), tabass (1987-2006), robate poshte badam (1992-2006), bafgh (1993-2006) and marvast (1997-2006), has been studied. wind data were obtained from the recorded data at yazd meteorology organization. the data were re...

The influence of quasi-realistic high-frequency wind variability for the probability distribution of surface waves and for the skill of the predictions with the wave model WAM is investigated. So far, the sensitivity of the surface wave field to high-frequency wind variability has been demonstrated only for idealized wave conditions or particular events using rather simplified high-frequency wi...

this paper presents a probabilistic optimal power flow (popf) algorithm considering different uncertainties in a smart grid. different uncertainties such as variation of nodal load, change in system configuration, measuring errors, forecasting errors, and etc. can be considered in the proposed algorithm. by increasing the penetration of the renewable energies in power systems, it is more essent...

[1] Dynamical behavior of the one minute resolution Polar Cap (PC) index was studied by using the 1995–2000 data sets. It was found that the probability distribution functions (PDFs) of the PC-index increments display a strong non-Gaussian shape in both positive and negative time intervals, depending on the time of an increment. This indicates that PC-index is not characterized by a global time...

a wind farm is a collection of wind turbines built in an area to provide electricity. wind power is a renewable energy resource and an alternative to non-renewable fossil fuels. in this paper impact of wind farms in power system reliability is investigate and a new procedure for reliability assessment of wind farms in hl1 level is proposed. in proposed procedure, application of fuzzy – markov f...

The comparison between Advanced Composition Explorer (ACE) solar wind data and simulations of magnetohydrodynamic (MHD) turbulence shows a good agreement in the waiting-time analysis of magnetic field increments. Similarity between classical discontinuity identification and intermittency analysis suggests a dynamical connection between solar wind discontinuities and intermittent MHD turbulence....

This paper reports stochastic properties of renewable wind and solar energy resources by studying their conditional probability distribution functions (cpdf) in different time lags. The empirical results are obtained for data of global horizontal irradiance measured by a single sensor and the power output of a single wind turbine, as well as for an averaged solar sensor field and an aggregated ...
